RAYMOND 1?. P/ZZELL/l DISPOSABLE BAG FOR MEDICAL USE SANILOK BAG SUMMARY OF THE INVENTION The plastic bag contains an area with a removable small circular disc surrounded by a spiral strip having weakened walls between convolutions. By removing the disc, a minimum size opening is obtained either for drainage or for insertion of ice. By removing a portion of the strip the size of the opening can be increased as desired. The strip exposing an adhesive ring has an adhesive coating protected by a removable backing. When the backing is removed, the adhesive coating can be moved into contact with a body surface whereby the bag is held in place.

The bag also contains a small extension with an elongated tip with an open conduit therethrough. This tip can be folded upon itself one or more times to seal the conduit, the folded tip being adapted to be held in sealed position by a piece of adhesive tape. The tip acts as a drain valve which is open when the conduit is open and is closed when the conduit is sealed.

BRIEF DESCRIPTION OF THE DRAWINGS In the drawings:

FIG. 1 is a top view of my bag;

FIG. 2 is an enlarged detail plan view of the drain opening therein;

FIG. 3 is a cross section taken along line 3-3 in FIG. 1;

FIG. 4 is a cross section taken along line 44 in FIG. 2;

FIG. 5 is a plan view of the structure shown in FIG. 4;

FIG. 6 is an enlarged detail view of the valve in open position;

FIGS. 7 and 8 illustrate various steps in closing the valve of FIG. 6;

FIG. 9 is a view similar to FIG. 1 but illustrating the opening ofa drain opening;

FIG. 10 illustrates an ice bag in accordance with my invention; and

FIGS. ll, 12 and 13 illustrate various uses of my invention.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Referring now to FIGS. 1-13, two plastic sheets 10 are edge sealed to form a hollow sealed plastic flexible bag. In one sheet, an area is scored or lined in such manner as to define a circular disc 12 surrounded by spiral strip 14 having a weakened wall 15 between convolutions. Strip 14 has an adhesive outer coating 17 covered by removable backing 19. An extension 16 also hollow and flexible and made of plastic communicates with the main interior of the bag via opening 18. Extension 16 has an elongated tip 20 with a hollow conduit 22 therein.

In order to use the bag to collect body fluid without discharge through the valve, the tip 20 is first folded upon itself one or more times and held in place by a piece 24 of adhesive tape. This action seals the valve and prevents leakage therethrough. The disc 12 and if desired a portion of strip 14 can be removed to provide a hole or opening of desired size. The backing is removed to expose the adhesive coating which can be placed in contact with the body with the opening aligned with the body opening to be drained. Garments 26 can be placed thereover.

In order to permit draining of the bag, the piece 24 can be removed, the tip unfolded and then a hose 28 can connect the unfolded tip, which now provides an open channel, to a pail 30 or other receptacle.

Finally, with the tip folded, ice 32 can be loaded into the bag via the drain opening, and the bag then folded upon itself to form an ice bag 34 which can be draped about the forehead or otherwise used.

While I have described my invention with particular reference to the drawings, such is not to be considered as limiting its actual scope. A

I-Iavmg thus described this invention, What IS asserted as new is:

l. A disposable bag having a variable size opening comprising, in combination,

first and second flexible sheets edge sealed together to form a hollow flexible structure,

an area in one of said sheets being constituted by a removable circular disc surrounded by separately removable concentric annular strips, thereby to form an opening of variable diameter, said disc and said strips being defined by scored concentric circular indentations in said one sheet, one of said sheets also having an aperture therein,

a valve-communicating via said aperture with the hollow interior of said structure and adapted for manual placement into either an open position or a closed-sealed position, said valve having an extension of the same material as said sheets, said extension being hollow and having a substantially triangular shape tapering from a first region, which surrounds said aperture and has a first diameter greater than the diameter of said aperture thereby forming an internal flange between said latter diameters, to an elongated tip having a second diameter less than said first diameter, said valve being closed by folding said tip upon itself and being opened by unfolding said tip.
